Answer:
see explanation
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ±
( subtract 2 from both sides )
x = - 2 ± 
Thus
x = - 2 -
≈ - 5.32 ( to 2 dec. places )
x = - 2 +
≈ 1.32 ( to 2 dec. places )
The answer will be option 6. angle.
Answer:
1.46 x 10⁶g
Step-by-step explanation:
Given parameters:
Weight of each bowling ball = 7.3 x 10³g
Number of balls in the bowling alley = 2.0 x 10²bowling balls
Unknown
The weight of the balls in the alley = ?
Solution:
To find the weight of the balls in the alley, multiply the mass of each balls with the total number of balls;
Weight of the balls = 7.3 x 10³ x 2.0 x 10²
Weight of the balls = (7.3 x 2.0) x 10³⁺²
Weight of the balls = 14.6 x 10⁵g
Therefore, the weight of the balls = 1.46 x 10⁶g
8%w-16%z
I think that this is the answer.
